[Bug 1730004] [NEW] Sound system(alsa) fails on resume from suspend

[Rob M]

Public bug reported:

Desktop system audio failure upon resume from suspend.  Event occurs
approx. 50% of time and can be remedied with sudo alsa reload.  Firefox
is program where problem is first noted but no sound from any source is
working.  Using GUI for sound setting will not correct problem.
